STONEWALL JACKSON MARTIN, OF-SALTILLO, MEXICO.

KNOTTER FOR COP-WINDING MACHINES.

Specification of Letters Patent.

Application filed November 9, 190 7. Serial No. 401,415.

To all whom it may concern:

Be it known that I, STONEWALL JACKSON H MARTIN, a citizen of. the United States, and a resident of Saltillo, Uoahuila, Mexico, have invented certain new and useful Improvements in Knotters for. Cop-VVinding Machines, of which the following is a specification.

In cloth factories where cop Winding machines are employed, it is necessary to join the ends of the .thread to be wound on the cops, which operation is usually performed by hand by tying the ends together. This is a slow and tedious operation, the knots freuently corning untied, or the ends of the t read beyond the knot are not of uniform length.

My invention is designed to provide a lmotter to be used as an attachment of the cop winding machine, which knotter ties j knots in a safe and rapid manner with a uniforin length of ends and without skilled labor,

.spective view of theknotting so that any inexperienced person may be able to uickly perform this service in a rapid and satisfactory manner. 1

The invention consists of certain novel constructions and combinations of parts as Will be hereinafter fully described with reference to the drawing, in which Fig "re 1 is a perspective view of my knotter attachment applied to a cop winding machine which is shown in dotted lines. Fig. 2 is a side View, and Fig. 3 is a face View of the linotting devices. Fig. 4 is a section through line 4-4of Fig. 8. Fig. 5 is a per- 7 bill or pinching jaws which. hold the thread, and Figs. 6, 6 6 and 6 are views showing the successive position of the parts of the knotter and the progressive stages of tying the knot. K Referring to Fig. 1, A represents an angle bar attached to the upper structure'of the cop windin machine in horizpntal position. This angle ar forms an elevated track rail on which my knotter attachment is suspended and shifted laterally to any position in which it may be required for-use. The attachment consists of the triangular hanger frame B having grooved pulleys b, b which ride upon the up or edge of the track rail and guard arms i I) which project below the railand prevent the hanger; frame from being accidentally dislodged. The lower convergent end of the hanger is .bolted'in an inclined position to the knotter Xg'gshown in detail in Figs. 2, 3 and 4. This consists of an elongated open frame 0 of generally rectangular shape having upon the inner edges of one of its side bars a row of rack teeth 0. Sliding on the parallel side bars of this frame is arranged a carriage D which has a range of adjustment from the lower end to the up er end of the rectangular frame. Within t is carriage D is arranged a rotary sleeve E having formed with it or attached to it a toothed pinion E? Whose teeth mesh with the rack teeth c on the side bar of the frame and which pinioh derives therefrom and imparts to the sleeve a rotary movement whenever the carriage D is slid longitudinally along the frame C. The rotary centrally within it a sliding stem E, seen in Fig. 4, which has a limited longitlidmal movement within the sleeve b t rotates rigidly with the sleeve. The 'slee72e E and stem E are fashioned at their up ei' ends into the two arts of the knottin zbifi, as'seen in Fig. 5. he sleeve E has a'fhook jaw e, and the sliding stem E has a holok jaw e. A longitudinal groove e in the sliding stem receives a rib e of the sleeve E, as shown in Figs. 3 and 5, which while securing independent lon gitudinal movementfor the stem E compels the rigid rotary movement of the sleeve E j and the stem E together. The rotary move ment of the sleeve E and stem E perform the function of laying the loop in tying the thread and the longitudinal sliding movement of the stem E effects the seizing and holding of the'thread and drawing it through the loop which is formed around the knotter,

The sleeve E, has, see Fig. 5, below its hook jaw e, a slot 6 which winds around the sleeve spirally and disappears into the curved face I a and the upper surface of the up er jaw e of the knotting bill, is rounded so t at when said upper jaw is down or inits tion for pinchin the thread the up er end of the knotting bil will resent a we rounded promote the casting off of the loop after the rnotting bill has drawn the threads through. the sen te 'will be morefully described hereafter.

The longitudinal sliding movement of the .stem E which controls the movement of the .upper jaw c of the knotting bill is imparted X by an elbow lever H, see Fig. 4, pivoted at 71.2

to th'e"carriage D and having one arm embracing a grooved lower end of the stem E, 1 and its upper end it. projecting up through Patented. March 30, 1999.

surface coinciding wit 1 the beveled face 6? to sleeve E has arranged as composed of the sleeveE, and stem E..-

lowest posi- 'tached to the upper end of the frame.

. F is a loop-forming wire arranged'in a generally longitudinal relation to the frame C and connected at its lower end to said frame and at-its upperend to the bearing lug of the I tappet pin. This loop-forming wire F at its lower end lies close down to the plane of the upper surface of the carriage D and as it'proceeds upward rises away from the frame 0,

as seen in Fig. 2, for thepurp ose hereafter described.

- The carria e D is provided on one side of the knotting bill with an upwardl projecting pin D and on the opposite side 0 the bill has rigidly attached-to it an upwardly projectin an le plate D formed with a notch in its si e adjacent to the knotting bill adapted to receive the threads t, t, to be tied and to hold them down in aplane which compels them to enter the groove 6 below the lower jaw of the knotting bill. The pin D and the angle plate 1) form thumb pieces which are grasped, respectively, by the thumb and forefinger of the right and left hand, as seenin Fig. .3 in dotted lines. Zlhe two ends of the thread to be tied are at the same time' grasped between the forefinger and the stem- D on the one' side and between the forefinger and the angle plate D on the other side, and the knot tying movement when the thread'is thus grasped is effected by the simple-upward advance of the carriage Din the direction of the arrows as will hereafter.

Attached to the bearing M at the upper end of the frame() there is a knife blade G, which be described more fully is arranged in the plane of the space between the angle plate D and the knotting bill and the function of this knife is to sever the end of the cord, at a. definite distance from the.

knot which is tied, after said knot has been tied by the upward movement of the carriage.- In order that the operation of tying the.

. knot may be better understood, l haveshown in Figs; 6, 6, 6 and 6, the successive positions of the parts in the several degrees of progress in forming the knot. When the two ends of the thread t, t are laid u'pon'tho stcin VI) and angle plate D; and grasped by the fingers, as shown in Fig. 3, the plane of the thread i is in the plane of the groove as i seen in Fig). 6, or beneath the lower jaw of the The elbow lever H provided elbow lever ll. As the carriage D is moved l upwardly in the direction of the arrow in hi 6, two things take place, the knotting bill is rotated by the engagement of its pinion E? with the teeth on thecarriage and passes to the position shown in Fig. 6. At

'the same time the ends of the thread t, t,

have risen upon the higher portion of the loop-forming wire -F and have carried the thread in an upward direction overthe in-' terior Scat'of thejaws e, c of the knotting bill. At this stage of the -o eration, the

upper jaw e of the knotting ill it will be seen is open and the space between the upper jaw and the lower jaw is in alinement with that portion of the thread 1 extending from the'knotting bill to its seat in the angle plate 1) so that when the knotting bill by a fur-"' ther rotary movement advances toward the" p'art'y of the thread, the threadwill be received between the jaws e and cf of the knot ting bill and when this takes place thelong tudinal sliding movement of t e stem bearing] 7 the upper jaw allows the upper 'aw tode-- scend and to pinch between 1t an the lower jaw .the thread at the point y. The action just described is shown as accomplished in.

Fig. 6 in which it will be seenthatthe loop is around the knotting bill and the knotting bill has seized the thread ".pre ratory to ingit while the loop is cast from thezsafiie. Tlie'movenient b which the kn'otting bill'ls;

pulling it through the loop or rat er forholdclosed is effected y the contact of the upper end 71/ of the levenI-f, see Fig. 4, agsginst-t'he] will'be'loo,

tappet-pinl, as seen'in vFig d. I I seen from Figs 4,. when said end h is thrust toward the knotting bi ll,-the other end of the I I pullsdown the stem E and I closes said knotti-ng billl" Asthe carriage still advances by reason of. the yielding character ofthetappetL-theithread at the point between the'kno'tting'bill'andthe angle plate D is broughtinto forciblec'ontact with the stationary knife G, as seen irrFi 6 ,"and

It onl remains now byan upward movement 0 the left hand portion of the thread t, t, to swing the loop over the pinched ends ofthe knot- 1 the thread is cut offa't a uniform an definite distance from the knotting bill.

ting bill, which forms a complete knot, as seen in Fig. 6. -V i'hen the threads are about to come in contact with the knife, the pinion v I E? is disengaged from the rackandis held yby he pressure of the lever H, and in its return the pinion'will grearlnthe same teeth. The object'in holding the pinion and I the bill stationary when cutting the threadsxf is to facilitate cutting the threads close tov the bills and also to make a clean crosscut of v the threads, for'if the pinion were to continue revolving, the ends or threads Wouldbe dragged 'acrrms the knife and the' threads would be left long and ragged.
